C#中可以用XmlDocument类操作Xml文件

例如要读取如下Xml文件

程式如下

其中XmlElement继承自XmlNode

XmlElement有GetAttribute()&GetElementsByTagName()等方法而XmlNode没有

不管使用XmlNode的ChildNodes属性还是XmlElement的GetElementsByTagName()方法获取的都是XmlNodeList

那这里就存在获取的XmlNodeList中的XmlNode到底是什么类型的问题

可以根据XmlNode的NodeType属性判断

如若等于XmlNodeType.Element就可以强转为XmlElement从而使用XmlElement的方法
